ATTORNEYS 2,930,542 YARN PACKAGE SUPPORT John Cocker m, Gastonia, NC, assignor to Cocker Machine and Foundry Company, corporation of North Carolina Application December 20, 1956, Serial No.622732 2 (Ilaims. (Cl. 242-130) Gastonia, N.C., a

package support including a holder component, for the mounting of a yarn package, which component lends itself to economical fabrication in quantity from sheet material; and a sustaining stud to which said component can be quickly and easily applied and from which it can be removed with equal facility, and with which said holder component is engageable against the possibility of accidental displacement during withdrawal of the yarn from the supported package.

Other objects and attendant advantages will appear from the following detailed description of the attached drawings, wherein:

Fig. l is a view, partly in elevation and partly in vertical axial section, of a support for a yarn package of the cop type, conveniently embodying my invention.

Figs. 2 and 3 are horizontal sectional views taken and looking as indicated respectively by the angled arrows II-II and IIIIII in Fig. 1.

Fig. 4 is a view similar to Fig. 1 showing a support for a yarn package of the cheese type, likewise conveniently embodying'my invention.

Figs. 5 and 6 show profiled blanks of sheet material from which the tubular package holding components of the supports of Figs. 1 and 4 respectively are fashioned.

With more detailed reference first to Figs. 1-3 of these drawings, the support therein illustrated comprises a holder component comprehensively designated 10 for reception of a yarn package P of the cop type, and a stud 11 for sustaining said holder component. As shown, the holder component 10 has a hollow frusto-conical body conformative in shape to that of the cop P, the body longitudinally split as at 12 and provided at the top and bottom respectively with plural circumferentiallyspaced inwardly-extending flat radial tongues '13 and 14. The distal ends of the tongues 13 and 14 of the two groups overlap each other and are provided with registering round-ended elongate openings 15 and 16 respectively. In accordance with my invention, the holder component 10 is fashioned from a profiled blank shaped as illustrated in Fig. 5 and there designated 17, said blank being cut or stamped from relatively thin stiif sheet material preferably of metal. In fashioning the component It), the blank 17 is rounded to conical form incident to which narrow margins along its side edge 18 are brought into overlapping relation in the region of the longitudinal split 12 in Fig. 1. With this accomplished, the tongues 13 are bent inwardly one after another into overlapping relation with incidental registering of the openings 15. In a like manner, the tongues 14 are successively bent inwardly into overlapping relation and their openings 16 at the same time brought into registry.

As will be noted from Fig. 1, the stud 11 has a rounded top end 20, and circumferential grooves 21 and 22 vertically spaced to correspond with the spacing of the tongue groups 13 and 15, the width of said grooves being equal substantially to the respective tongue groups. larly noted from Figs. 2 and 3 that the width of the opening in the tongues 13 and 14 is slightly less than the diameter of the stud 20. In applying the holder component 10, the tongue groups 13 and 15 are successively impaled upon the stud 11, and said component is slid down the stem until, by spring action, the tongue groups snap into the respective grooves 21 and 22. Since the body of the holder is fashioned from very thin sheet material as shown, the tongues 13 and 14 yield to slight spreading as they are forcibly depressed over the rounded top end of the stud 11 so that their engagement into the grooves 21 and 22 in the stud is effected by snap action as above described. By attendant circumferential expansion of the body the rounded end portions in the tongues are caused to snugly conform into the grooves. Obviously, this engagement is such as to permit free rotation of the holder component 10 about the stem during withdrawal of the yarn tangentially from the supported yarn package. During endwise withdrawal of the yarn from the package the holder component will remain stationary, of course, as will be readily understood.

Except for having a cylindrical body to conform with the core of the cheese type yarn package P, the holder component 10 of Fig. 4 is identical with the component 10 of the first described support. The holder component It) is fashioned in the same way from a profiled blank 17' of suitably stiff springy sheet material shaped as shown in Fig. 6. In order to dispense with repetitive description, all the elements in Figs. 4 and 6 having their counterparts in the form of support shown in Figs. 1-3, are identified by the same reference numerals, with addition in each instance however of a prime for convenience of more ready distinction.

Having thus described my invention, I claim:

1. As a new product of manufacture, a support for a hollow yarn package, said support comprising a holder integrally fashioned to tubular configuration from a profiled blank of sheet material with groups of inwardlydirected radial arms top and bottom, the distal ends of the arms of the respective groups being in mutual overlapping contact with each other and having registering apertures at their distal ends; and a mounting stud over which the apertured arms of the holder are impaled with capacity for free rotationof the holder about the stud.

2. As a new product of manufacture, a support for a hollow yarn package comprising a longitudinally split tubular holder component over which the package is mounted, said component being fashioned from a profiled blank of thin stiif sheet material with plural inwardly directed annularly-spaced radial tongues respectively at the top and bottom, the ends of the tongues of the respective groups overlapping each other and being provided at their distal ends with longitudinal registering round-ended slot openings; and a mounting stud of a diameter somewhat larger in diameter than the width of the tongue openings, having circumferential grooves spaced to correspond with the spacing of the two groups of tongues of the holder component and of a width substantially equal to the aggregate thickness of the tongues of the respective groups whereby, upon impalement of the holder component on the stud, the tongue groups snap into the grooves of the stud.
